to keep the original formatting, do not use form builder to add additional form elements.
Instead, add the additional form elements manually.
Place your cursor where the form element should go, then go to Insert -> Form -> Text box.
after the form elements are added, double click the DataAssist insert record behavior to bind the new form element to the database columns.
NOTE: when editing the solution pack files with the extensions, the solution pack files must be at the root of the Dreamweaver site.
